Expert Level Desert/GP racer: I typically run the Kenda Parker 772 rear for desert. But needed a track tire for a GP in Utah for the weekend. I highly recommend this tire. Works well in all aspects; grip cornering braking and high speed stability. So well that I have been still using it for Desert practice. I'm actually surprised at how well this tire works in the Nevada desert. No chunking fantastic grip and long lasting wear even at my level of riding. I have been running Kenda's for a year now and these are the only tires I see that do not break down and submit to severe chunking in all conditions. The wear well round off nicely so you can re groove the tire for even longer life. Give it a shot you will not be disappointed.
